[0001] The utility model is suitable for green moss cleaning tool field, provide a kind of avoiding type green moss cutting hand-held tool. BACKGROUND

[0002] Green moss in water body usually grows under the environmental conditions of water body eutrophication and sufficient illumination. With the accumulation of eutrophic substances in water body, such as the increase of elements such as nitrogen and phosphorus, the propagation speed of green moss is significantly accelerated, and especially in still water or slow-flowing water body such as lakes, ponds and rivers, green moss is easy to cover the water surface or the bottom. This phenomenon is often seen in aquaculture water area, urban water body and agricultural irrigation water system, causing water body eutrophication and forming negative ecological effects.

[0003] At present, the traditional green moss fishing method mainly relies on manual tools such as net bag. Although this method can clean green moss to a certain extent, it has many limitations in design and operation mode, and the efficiency is low. Each time fishing needs repeated operation, and green moss is easy to wind in the net bag, so it needs to be arranged many times.

[0004] Green moss often entangles with submerged plants during growth, especially filamentous green moss is easy to wind on the stems and leaves of submerged plants, which not only increases the difficulty of fishing, but also may damage the growth structure of submerged plants. The currently used traditional fishing equipment often cannot avoid this situation, but may uproot the submerged plants during operation, causing ecological damage. The high-speed operation of traditional mechanical fishing equipment easily damages the roots and stems of submerged plants, disturbs the ecological environment of water bottom, affects the normal growth of aquatic plants, and further destroys the ecological balance of water body.

[0033] Outer cutter 21 and inner cutter 22 are one-to-one corresponding, when inner ring layer 12 is located at initial position, outer cutter 21 and inner cutter 22 are one-to-one corresponding and set, at this time, adjacent outer cutter 21 has gap, and filamentous moss will fall into the gap, and when inner ring layer 12 relatively rotates on outer ring layer 11, inner cutter 22 is driven by inner ring layer 12 and cross shearing motion occurs with outer cutter 21, and moss existing in the gap is cut off.

[0034] Preferably, the inner ring layer 12 is provided with an inner ring groove 121 on the side close to the outer ring layer 11, and one end of a connecting line 1211 is fixedly connected in the inner ring groove 121, and the other end of the connecting line 1211 is installed on the output end of the driving device. The output end of the driving device pulls the connecting line 1211, thereby driving the inner ring layer 12 to rotate on the outer ring layer 11.

[0035] Preferably, the connecting part 3 and the handle 4 are both provided with cavities that are mutually through, and the connecting line 1211 is arranged in the cavities, thereby enabling the two ends of the connecting line 1211 to be connected to the inner ring layer 12 and the driving device respectively. Further, the connecting part 3 is provided with a rotatable pulley 31, which functions as a reversing device and can reverse the connecting line 1211 wound on the inner ring layer 12 to the inside of the handle 4.

The other end of the connecting line 1211 is fixed in the inner ring groove 121 of the inner ring layer 12, and pulling the connecting line 1211 drives the inner ring layer 12 to rotate relative to the ring groove 111 of the outer ring layer 11. At this time, the inner cutter 22 is driven by the inner ring layer 12 to cross shear with the outer cutter 21, so as to cut the moss in the gap. When the missing part of the missing gear 54 rotates to the sliding part 52, the inner ring layer 12 is reversed under the elastic potential energy release of the elastic member 123, and the cross shear motion opposite to the previous one is generated again, at the same time, the sliding part 52 is reset under the pulling force of the connecting line 1211. After the cutting action is completed, the device is automatically reset, and the process is repeated.

[0042] Therefore, the device can efficiently fish the moss floating on the water surface and underwater through the net 10 at the bottom of the net ring 1, and effectively solve the problem of moss entanglement through the outer cutter 21 and the inner cutter 22 of the cutting part 2. When the moss cannot be directly fished due to entanglement with submerged plants, the cutting part 2 cuts the moss through cross shear motion, avoiding the frequent arrangement problem caused by the entanglement of the traditional tool, and significantly improving the fishing efficiency. In addition, the circular arc design of the outer cutter 21 and the inner cutter 22 not only ensures the safety of the user, but also avoids the damage to the water ecology. The net ring 1 is made of stainless steel, which ensures the structural strength and durability.

[0043] Overall, the device improves the efficiency of the moss cleaning, effectively protects the ecological balance of the water body, and is especially suitable for the moss treatment requirements of aquaculture water area, urban water body and agricultural irrigation water system.
